According to data from the European Copernicus service on climate change, temperatures rose 0.1 ° C in June from the previous record of June 2016 and it was mainly in Europe that it was very hot, with a temperature of about 2 ° C above normal.

Several records were broken last week in European countries hit by heat due to a mass of hot air coming from the Sahara desert.

Temperatures exceeded normal seasonal temperatures by 10 ° C in Germany, northern Spain and Italy, and in France, which hit a record high of 45.9 ° C on Friday.

Combining satellite data and historical data, Copernicus estimated that June's temperature in Europe was 3 ° C above the average between 1850 and 1900.

"Our data shows that temperatures in southwestern Europe last week were abnormally high," said European service chief Jean-Noel Thépaut.

"Although it was exceptional, we are likely to experience more of these events in the future because of climate change," he added.

The Copernicus team said it was difficult to attribute this record "directly" to climate change, but a group of scientists who focused on the heat wave in France concluded today that it was "at least five times more likely" to have been caused by climate change.

The last four years have been the hottest recorded in the world, a sign of warming caused by record levels of greenhouse gas emissions.

The planet has already gained 1 ° C since the pre-industrial era, resulting in a multiplication of extreme weather events, from heat waves to heavy rains and storms.
